What are the reasons for brake pad noise during braking?
4 Answers
The reasons for brake pad noise during braking are: 1. Rust on the brake disc or brake pads; 2. The brake pads are new; 3. Excessive wear on the brake disc and brake pads; 4. The brake pads are installed incorrectly or are of the wrong model; 5. Use of inferior or overly hard brake pads; 6. Abnormal brake caliper or lack of brake fluid; 7. Presence of foreign objects between the brake drum or disc and the pads. Solutions for brake pad noise during braking: 1. Apply butter or special lubricating oil at the connection between the brake pads and the brake caliper; 2. Regularly inspect and replace the brake pads; 3. Regularly adjust the brakes; 4. Avoid frequent use of the brakes.
I've been driving for many years, and there are usually several reasons for squeaky brakes. The most common one is that the brake pads are worn too thin, causing the metal backing plate to directly rub against the brake disc, producing a screeching sound. Or, after driving on gravel roads, small stones may get stuck in the gaps of the brake pads, causing unusual noises when braking. Additionally, in humid weather, rainwater or moisture can cause slight rusting on brake components, resulting in noise when braking. If you've just replaced the brake pads or discs, the harder material may need a break-in period, and the noise should disappear after driving a few hundred kilometers. I recommend regularly checking the thickness of the brake pads; if they're below 3mm, they should be replaced to avoid worsening the problem and compromising safety. When washing your car, pay attention to cleaning the brake areas to remove dust and debris. Don't underestimate these small noises; ignoring them could lead to reduced braking performance. It's always good to check your car's condition before heading out.
Commuting to work by car can be frustrating when the brakes start making noise. From my personal experience, most of the time it's because the brake pads need replacing—excessive wear leads to metal-on-metal friction. Alternatively, misalignment during installation can cause uneven contact between the brake pads and rotors, resulting in noise. For new cars or after replacing brake components, there might be a break-in period where the noise naturally fades after some driving. Also, driving after rain can cause rust on the brake discs, leading to squeaking. I always get it checked as soon as possible since brake issues directly impact driving safety. I recommend having the brake thickness and evenness inspected at a shop every six months to catch problems early. Using gentle braking techniques in daily driving and avoiding sudden stops can also extend their lifespan. Safety is no small matter—paying attention to these details can save a lot of hassle.
I just started learning to drive and got quite nervous when I heard the brakes squeaking. After checking, I found that it's usually due to the material of the brake pads, such as using hard pads which create more friction and noise. Or it could be foreign objects like small stones getting mixed in and causing friction sounds. This is especially common during cold starts in winter. Solution: First, try lightly pressing the brakes a few times to remove rust; if the noise persists, get it inspected immediately. The health of the braking system is a matter of life and death, so don't delay repairs. Choosing genuine factory parts for installation is more reliable. Develop the habit of regular maintenance to ensure smooth driving.
